摘要
通过CFRP筋体外预应力加固钢筋混凝土梁的试验,研究了混凝土标号、原梁配筋率、体外预应力束弯折角度、损伤度及带载水平对加固梁刚度的影响。通过研究得出了相应结论。其研究成果对CFRP筋体外预应力加固技术具有一定的借鉴作用。
The article studies the influence of concrete grade,original beam reinforcement rate,external pre-stressing bind bending angle,injury degree and loading level on the rigidity of the reinforced beam by the experiment of CFRP tendon external prestressed reinforced steel concrete beam.The article gives the relative conclusion of the study.Its study result has some references for CFRP pre-stressing reinforcing technology.
